All living things are made up of cells. The structures of different types of cells are related to their functions. They may be specialised in order to carry out a particular job.
- EG: Root Hair Cells: Tiny hair-like structures which increase surface area.
- Xylem: Long, thin, hollow cells used to transport water through the stem and root.
- Nerve Cells: Long, slender axons which can carry nerve impulses.
- Nucleus: Controls the activities of the cell.
- Cytoplasm: Where chemical reactions take place.
- Cell Membrane: Controls what goes in and out of the cell.
- Mitochondria: Where the most energy is released in Respiration.
- Ribosome's: Where Protein Synthesis occurs.
- Cell Wall: Used to strengthen the cell.
- Chloroplasts: Absorb light energy to make food.
- Permanent Vacuole: Filled with Cell Sap.
